The effect of mild hypothermia on neuronal apoptosis and Bcl-2,Bax in the focal cerebral ischemia in rats / 临床神经病学杂志

ABSTRACT

Objective To study the effect of mild hypothermia on neuronal apoptosis and Bcl 2,Bax during cerebral ischemia in middle cerebral artery occlusions(MCAO) in rats.Methods The model of MCAO was set up in rats using the Longa's way,and mild hypothermia was treated for 0.5h,1h,3h. After reperfusion(24h) the rat brains were cut into three sections for TUNEL staining and Bcl 2?Bax protein immunohistochemical staining.Results 1)The numbers of apoptotic cells and Bax cells in the mild hypothermia group(1h, 3h) decreased remarkable as compared with the control group( P
